Detailed Description

template<class GridImp, template< class > class HierarchicIteratorImp>
class Dune::HierarchicIterator< GridImp, HierarchicIteratorImp >

Enables iteration over all codim zero entities in a subtree See also the documentation of Dune::EntityPointer.

Mesh entities of codimension 0 ("elements") allow to visit all entities of codimension 0 obtained through nested, hierarchic refinement of the entity. Iteration over this set of entities is provided by the HierarchicIterator, starting from a given entity. This is redundant but important for memory efficient implementations of unstructured hierarchically refined meshes.

Note: The HierarchicIterator interface is deprecated. Use the EntityIterator interface instead.
